Rogue Pictures have unleashed the first official trailer for the documentary film, Catfish.

The film, which was directed by first-timers Henry Joost and Ariel Schulman, was a huge hit with audiences and critics alike when it debuted earlier this year at the Sundance Film Festival, and now it’s gearing up momentum ready for a full US release.

Synopsis: Nev, a 24-year-old New York-based photographer, has no idea what he’s in for when Abby, an eight-year-old girl from rural Michigan, contacts him on MySpace, seeking permission to paint one of his photographs. When he receives her remarkable painting, Nev begins a friendship and correspondence with Abby’s family. But things really get interesting when he develops a cyber-romance with Abby’s attractive older sister, Megan, a musician and model. Prompted by some startling revelations about Megan, Nev and his buddies embark on a road trip in search of the truth.

It’s an interesting trailer, considering it’s tough subject matter. I’m curious to see what sort of audience the film attracts when it opens in the US on September 17, 2010. Hopefully it’ll be enough to convince Relativity Media and Rogue Pictures to release it in the UK.
